The Role of a Computed Tomography-based Image Registered Navigation System for Natural Orifice Transluminal Endoscopic Surgery: a Comparative Study in a Porcine Model

Annotated screen capture of the image registered-guided natural orifice transluminal endoscopic surgery (IR-NOTES) that was displayed during the guided procedures. The upper left part of the screen shows a 3D display of the general anatomy and the location of scope tip with respect to the rendered organs. The upper right part of the screen shows the virtual endoscopic image that is generated from the structures extracted from preoperative computed tomography (CT). The lower part of the screens shows the CT re-formatted in the local frame with respect to the scope tip.

To improve minimally invasive procedures by providing real-time images showing instrument positions in anatomic context.
To develop systems that are low in cost, adapt easily to commercial instruments, and are intuitive to use, based on open source software.
